  • Patent number: 7910848
    Abstract: Keypad devices have become commonplace in everyday life. They are part of our everyday life, in the form of pocket calculators, telephones, remote control devices, and cellular phones. Cleaning these keypad devices is problematic, since they have a large number of actuatable keys, due to the functions to be performed. As a mechanical interface in the keypad device, each key is a critical weak point in terms of maintaining a tight seal. An easy-to-clean keypad device, in particular an emergency call device, has a main body, an electronic assembly—which includes circuit elements and is installed in main body—a closing shell and keys, which are installed in closing shell and are designed to mechanically actuate the circuit elements. Closing shell with installed keys is a first preinstalled assembly, and main body with installed electronic assembly is a second preinstalled assembly. The first and second preinstalled assemblies are interconnected such that they may be separated.

  • Patent number: 7538645
    Abstract: An electromagnetic relay is provided which enables a coating process with a coating agent even after being mounted on a printed circuit board having undergone reflow heating by preventing invasion of water while maintaining air permeability. A main body making up the electromagnetic relay includes an electrical contact portion, electromagnetic driving portion and molded resin base and is covered with the molded resin cover. One or more through holes are formed by applying laser beam from a rear side of the molded resin cover. A spot diameter of each through hole on a surface of an outside of the molded resin cover is 0.1 ?m to 10 ?m. Instead of the molded resin cover, through-holes each having a size of 0.1 ?m to 10 ?m may be formed by applying the laser beam to the molded resin base.

  • Patent number: 7495189
    Abstract: A miniature circuit breaker is disclosed with a latch for continuously opening and closing a contact point with a contact lever on which the moving contact member is molded. A toggle lever gear with a link connected to a switching handle and a coupling element are provided, the coupling element connecting the link with the contact lever, which toggle lever gear can be brought from a first stable position (switched-on position) into a second stable position via a dead-center position by a tripping mechanism. The contact lever can be rotated and the contact point can be permanently opened. A compression spring is provided which acts on the link, the force of which acts approximately in a direction of the longitudinal extent of the link in the switched-off position, and thus at the beginning of the switching-on process, and transversely thereto in the switched-on position.

    Abstract: An air guidance device is for cooling a switch part of an electrical switch. It includes at least one air guidance element arranged at a distance from the switch part to be cooled, forming at least one air duct which runs vertically when the switch is in the installed position. The air duct includes an inlet area, which points downwards, for cooling air to flow therein, and having an outlet area, which points upwards, for cooling air to flow out thereof. In order to improve the heat dissipation, the air guidance element is shaped such that the inlet area tapers in the direction of the outlet area.

  • Patent number: 6960736
    Abstract: A switching gas damper for low-voltage power circuit breakers, is arranged as an attachment above the arcing chambers for additional damping, deionization and cooling of the switching gases. The switching gas damper includes a cuboid enclosure with separate inlet openings to receive switching gas flows from each arcing chamber in the low-voltage power circuit breaker. Separate outlet channels are formed by channel walls and/or by deflection elements and are routed on both sides of the power circuit breaker. A variable arrangement of the deflection elements and outlet channels makes it possible to produce a number of mutually separate flow paths, with different desired damping and cooling characteristics, as a function of the gas amounts that occur and of the characteristics of the arcing chambers that are used.

  • Patent number: 6917003
    Abstract: A switch is used to detect opening/closing of a car door or the like in a vehicle, and the switch can be provided with a nice operation feeling and stable performance. Thin corrugated sections are provided on a cover that covers a switching-element, connection points of lead wires and lower portions of a housing of the switch. The switch performs a nice operation feeling with quick response, as upon pushing the cap, the corrugated sections of the cover expand outward to prevent air in the switch from being compressed.
